BACKUP WHAT IS IT? Copying and archiving computer data so it can be used to restore originals following loss of data. O Allows user to recover data if it is lost due to deletion or corruption. O Allows user to recover data from an earlier time. DATA REPOSITORY MODELS STORAGE MEDIA Regardless of the repository model, data must be stored on some data storage medium. UNSTRUCTURED e.g. A stack of CD-R or DVD-R media with minimal backup information. MAGNETIC TAPE Has long been the common medium for bulk data storage and backup. FULL ONLY/SYSTEM IMAGING Contains complete system images from specific moments in time. HARD DISK Spinning magnetic device used in many computers and external drives. INCREMENTAL Organizes data into small changes between points in time. OPTICAL STORAGE Writable CDs, DVDS & Blu-Ray discs. DIFFERENTIAL FLOPPY DISKS Saves data since the last full backup. Used for backing up in the 1980s and 1990s; now obsolete. REVERSE DELTA SOLID STATE STORAGE Stores a recent 'mirror' of the source data and a series of differences be- Flash memory, thumb drives & USB flash drives. tween the mirror and previous states. REMOTE BACKUP SERVICE Backs up over the Internet to a re- mote location; can protect companies against worst-case scenarios. CONTINUOUS DATA PROTECTION System immediately logs every change on the host system. BUSINESS CONTINUITY & DISASTER RECOVERY Refers to an organization's ability to recover from an unexpected event and resume operations. RECOVERY TIME OBJECTIVE DATA BACKUP The time it takes for a system to be completely up and running. Central to any disaster recovery plan, this determines: O If backup processes are effective. O If they are actually being imple- mented by the involved personnel. RECOVERY POINT OBJECTIVE Measures the ability to recover files by specifying a 'point-in-time' restore of the backup copy. BUSINESS CONTINUITY & DISASTER RECOVERY PLANNING: THE BASICS GETTING STARTED O Create a business impact analysis that defines your company's most crucial processes and systems and the effect that an outage would have on your business. e Test your continuity plan regularly to reveal weaknesses and make changes as necessary. O Evaluate your company's performance during each test, working toward continual improvement.
